Contractions at 7 Months Pregnant: Braxton Hicks vs. True Labor

At 28–30 weeks (7 months), uterine contractions are common. Distinguishing Braxton Hicks (practice contractions) from preterm labor is critical for maternal and fetal health.

Braxton Hicks (False Labor)

• Irregular, unpredictable frequency
• Mild, often painless tightening
• Felt mainly in anterior abdomen
• Subside with hydration, rest, position change, or emptying bladder
• No cervical change

True Preterm Labor Contractions

• Regular, increasing frequency (e.g., every 10 minutes → every 5 minutes)
• Progressive intensity and duration
• Start in lower back/abdomen and radiate to thighs
• Persist despite rest and hydration
• Associated with cervical dilation and effacement

Warning Signs: Call Provider Immediately

• ≥6 contractions per hour before 37 weeks
• Menstrual-like cramping, pelvic pressure, low backache
• Vaginal bleeding or fluid leak (rupture of membranes)
• Change in discharge (mucus plug, watery)

Evaluation

Assessment includes fetal fibronectin testing, cervical length ultrasound, and tocometry. If preterm labor is confirmed: tocolytics, corticosteroids for lung maturity, magnesium sulfate for neuroprotection (<32 weeks), and antibiotics if GBS positive or membranes ruptured.
